Married At First Sight's Davina Rankin has spoken out about her controversial turn on the show, describing the experience as "traumatic" and slamming Nine for their inadequate support in the wake of abuse and death threats on social media.

"I barely got out of this whole ordeal alive," the Brisbane Instagram model and businesswoman told the ABC.

The dramatic storyline saw Rankin branded a "homewrecker" by viewers on social media; the star said she also received threats of violence and death threats.

"It's just crazy because people believe so much," she told the ABC, saying she feared going out to the shops in case her detractors spotted her.

"They genuinely believe I had an affair on my husband. This was a guy I'd only known for a week – we're not boyfriend and girlfriend, let alone husband and wife."

Rankin also targeted Nine for fuelling the negative online reaction, and offering unsatisfactory professional support in the wake of the abuse.

She said she would be meeting with Queensland Labor MP Dianne Farmer to campaign against cyberbullying.

"We need something put in place that people can't feel as attacked," Rankin told the ABC.

"Especially when it's coming from magazines or the network – posting memes about them, it gives the young people the right to do that themselves.

"Set better examples. Social media posts are up there forever, people feed off the hate and it gets to a point of no return."

Representatives for Nine have been approached for comment.

Rankin, who avoided social media and interviews at the height of the scandal, first broke her silence in an emotional YouTube video posted on Sunday.

"Copping such a huge amount of hate is something that I'm not really used to and, to be honest, it really shook me," she said in the video.

"It's been a really, really hard and traumatic experience for me," she said.

Rankin's jilted partner on the reality hit, Ryan Gallagher, had previously sought to quell the frantic reaction to his ex-wife's behaviour, saying the two were "civil" following their exit from the show.

"We don't hate each other, but we haven't been in touch since, either," he told Fairfax Media last month.

Nine this week came under fire from another contestant on their mammoth hit, with Dean Wells accusing the show's producers of "forcing" him to make sexist comments during Tuesday's controversial boys' night.
